Mel B’s ex-nanny Lorainne Gilles has revealed shocking details about her relationship with the former Spice Girl.

Making the claims in a 128-page libel lawsuit, the 26-year-old German blonde claimed Mel acted as "cameraman" for threesome sex movies involving the pair and Mel’s ex-husband Stephen Belafonte.

Hitting back at the star, who dragged her into a bitter divorce battle, Lorraine said the filmed sessions made her feel "very uncomfortable".

She stated she believed the sex footage is on mobiles owned by the couple – and that she’s terrified of it appearing online.

“These recordings would be extremely embarrassing to me and my family… I do not want any of them to become public,’ her statement read.

When Mel B filed for divorce from Stephen back in March, she alleged that their nanny had an affair with her husband behind her back, fell pregnant by him and then had an abortion.

She also accuses Stephen and Lorraine of taking money from her. However Lorraine has steadfastly denied the baby she was carrying was Belafonte’s.

In the dossier, lodged with California’s Superior Court, Lorraine revealed how all three enjoyed sex together.

She said in the papers: “My sexual and employment relationship with Melanie continued for approximately seven years until September 2016.

“During my time with Melanie, she and I had sex sporadically, sometimes having sex multiple times in a week.

“On the other hand I never had any sexual relations with Stephen without Melanie’s instruction and without ­Melanie’s actual or apparent consent.

“At no point did I represent to Melanie that I was pregnant with Stephen’s child.

“The only times Stephen and I had sex was when Melanie instructed Stephen and I to do so. Or when Melanie herself invited her husband to join us in the bedroom, at which point Melanie would often serve as the “camera man” and record the sexual encounter or take part in the menage a trois herself.”
